ADMINISTRATIVE REPORT
MEETING DATE: 8/13/2025 AGENDA CATEGORY: Consent – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 7/29/2025
SUBJECT: Contract Change Order No. 80 to Agreement No. 19-069 with Security Paving Company (increasing compensation by $100,409.39; revised not to exceed $152,119,004.58) for the Centennial Corridor Mainline Project. (Wards 1, 2, & 3)
RECOMMENDATION:
Staff recommends approval of the change order.
BACKGROUND:
The Centennial Corridor Mainline Project (Project) proposes to extend State Route 58 (SR -58) from the current terminus as a freeway at State Route 99 (SR -99) to the Westside Parkway. At the SR -58/SR-99 interchange, the Project adds a collector -distributor on the northbound SR -99 and constructs a new northbound to westbound connector. The Project also includes various local road improvements including; realignment and introducing cul-de-sacs at the end of local roads along the corridor, widening and realignment of Chester Avenue at SR -58, and construction of a traffic signal at the eastbound SR -58 ramps/Brundage Lane intersection (which is part of the SR -58/Cottonwood Road interchange). This Project was awarded in July of 2019.
Change Order No. 80 increases compensation to the contractor for the cost of colored concrete barrier.
The City and Contractor had been in dispute over the cost of colored concrete barrier, the limits of which were unclear in the project plans. Both parties went through the claims process. This change order is in accordance with the Dispute Resolution Board’s recommendation under Potential Claim Record No. 36 resulting in an increase of $100,409.39.
The Contractor has refused to sign th is change order alleging additional time and money. However, the Contractor needs to substantiate the request for time and money. In a good faith effort to make payments to the Contractor, staff recommends unilateral approval of th is change order using the engineer's calculated quantities and without the Contractor's signature. If the Contractor later submits acceptable justification for revisions to this change order, staff will review the additional information and, if changes are warranted, a supplemental change order may be in place on a future City Council Agenda.
FISCAL IMPACT:
The sum of all change orders to date on this project reflects a total cost increase of $5,105,348.33 which results in a 3.47% increase of the original contract amount as illustrated below:
Original Contract Amount = $147,013,656.25
Previous Change Orders = $5,004,938.94
Current Change Orders = $100,409.39
Amended Contract Agreement after CCOs = $152,119,004.58 Net Increase to date = $5,105,348.33
There is no General Fund impact associated with this change order.
Federal, State, and Local f unding for these change orders is available in project TRCC21 Centennial Corridor Phase 4 Mainline.
